VAALCO ENERGY, INC. ANNOUNCES

FOURTH QUARTER AND FULL YEAR 2016 RESULTS

HOUSTON – MARCH 13, 2017 – VAALCO Energy, Inc. (NYSE: EGY) today reported results for the fourth quarter and full year 2016.

Fourth Quarter 2016 and recent highlights:

Generated operating income of $0.8 million in the fourth quarter of 2016 compared with a loss of $64.7 million in the fourth quarter of 2015, an improvement of $65.5 million

Closed acquisition of additional 2.98% working interest (3.23% participating interest) in the Etame Marin block offshore Gabon

Produced an average of 3,682 barrels of oil equivalent per day (BOEPD) in the fourth quarter of 2016, above the guidance range of 3,300 to 3,600 BOEPD

Successfully completed workovers on the South Tchibala 2H and Avouma 2H wells increasing net production to 4,600 barrels of oil per day (BOPD) in January 2017

Reported year-end reserves totaling 2.6 million barrels of oil equivalent (MMBOE), reflecting 87% reserve replacement in Gabon for 2016, with no capital spending on drilling new wells

For the fourth quarter of 2016, VAALCO reported a loss from continuing operations of $3.4 million, or a loss of $0.06 per diluted share. In the same period in 2015, the Company reported a loss from continuing operations of $70.5 million, or a loss of $1.21 per diluted share. The loss in the fourth quarter of 2015 included a $52.1 million non-cash impairment charge primarily due to lower projected oil prices.

As a result of the Company’s decision to discontinue operations in Angola and withdraw from its joint operating agreement, the operating results of the Angola segment have been classified as discontinued operations for all periods presented in the consolidated statements of operations. The loss from discontinued operations in the fourth quarter of 2016 totaled $0.3 million, or $0.00 loss per diluted share. In the fourth quarter of 2015, there was a loss from discontinued operations of $10.3 million, or $0.18 loss per diluted share.

The average realized price for crude oil in the fourth quarter of 2016 was $46.62 per barrel, up 19% from $39.18 per barrel in the fourth quarter of 2015 and up 10% from $42.31 per barrel in the third quarter of 2016. Adjusted EBITDAX totaled $2.2 million in the fourth quarter of 2016 compared with $3.3 million in the same period of 2015, and $4.6 million in the third quarter of 2016.

Adjusted EBITDAX is a Non-GAAP financial measure and is described and reconciled to net loss in the attached table under “Non-GAAP Financial Measures.”

Cary Bounds, VAALCO’s Chief Executive Officer commented: “I am proud of the talented team at VAALCO and commend them for the meaningful accomplishments we were able to achieve together in 2016. We operated in a safe and environmentally responsible manner without a recordable incident in 2016. We successfully completed two well interventions utilizing a more cost effective hydraulic workover unit versus the traditional method of mobilizing a drilling rig and restored over 1,000 BOPD of net production. We added additional interest in our Etame Marin block offshore Gabon through an acquisition. We were able to replace reserves almost equal to our production rate, while spending no capital on drilling new wells. In sum, we were able to execute on our corporate strategy and enhance value through operational successes, cost reductions and opportunistic transactions.”

Bounds continued, “Looking ahead into 2017, we will maintain our focus on maximizing margins, delivering on our operational guidance and executing on our strategic plan. Financially, we are looking to continue to bolster the balance sheet and build a solid foundation of cash for future development projects. In the fourth quarter of 2016, we entered into additional crude oil put contracts in order to protect our cash flow and minimize our downside risk in 2017, while preserving upside related to oil price changes. Operationally, we are evaluating development opportunities on our offshore Gabon asset that add value and minimize decline. The Company is methodically seeking similar opportunities in West Africa and internationally, where our strong management and technical expertise gives us an advantage when looking at growth opportunities. By continuing to execute our strategy and deliver results, VAALCO is poised to add value to its shareholders.”

Etame Marin Additional Interest Acquisition

On November 22, 2016, VAALCO closed the previously announced acquisition to acquire an additional 2.98% working interest (3.23% participating interest) in the Etame Marin block from Sojitz Etame Limited (“Sojitz”), which represents the full interest owned by Sojitz in the concession. This acquisition will continue to provide upside potential in net production and reserves for VAALCO moving forward, without requiring any additional staffing. The transaction was funded with cash on hand.

Sale and Pending Sale of U.S. Properties

On December 29, 2016, the Company closed the previously announced sale of its interests in two Granite Wash gas wells on the Hefley lease in North Texas. The two wells in total were producing approximately 69 BOEPD net to VAALCO.

On October 17, 2016, the Company signed a letter of intent to sell its entire acreage interests in the East Poplar Unit in Montana for $250,000. The transaction is expected to be concluded during the first half of 2017.

Offshore Gabon

In the fourth quarter of 2016, production decreased 4% from 3,772 BOPD in the third quarter of 2016 to 3,620 BOPD. This was primarily due to the electrical submersible pump (ESP) failures at the Avouma field. As previously reported, VAALCO successfully completed workover

operations with a cost effective hydraulic workover unit on the South Tchibala 2-H and the Avouma 2-H wells and the wells were put back on production. The entire operation was conducted safely and efficiently with no injuries or threats to the environment. All personnel and equipment utilized during the combined operations on the two wells have been demobilized. The detailed inspection of the failed ESP components continues and the Company expects that the cause of the failures will be determined during the first half of 2017.

Onshore Gabon and Equatorial Guinea

VAALCO continues to examine alternative, lower cost development options for discoveries in the Mutamba Iroru permit onshore Gabon, and in Block P offshore Equatorial Guinea. These discoveries present unique development opportunities that will be re-evaluated as prices continue to recover.

2016 Fourth Quarter Financial Results

Total oil and natural gas sales for the fourth quarter of 2016 were $15.3 million, compared to $17.5 million for the same period in 2015, and $14.6 million in the third quarter of 2016. Fourth quarter 2016 revenue was positively impacted by the increase in realized pricing, but negatively impacted by reduced sales volumes compared to the fourth quarter of 2015 and the third quarter of 2016.

During the fourth quarter of 2016, VAALCO sold approximately 326,000 net barrels of oil at an average price of $46.62 per barrel, compared to 457,000 net barrels at an average price of $39.18 per barrel in the fourth quarter of 2015, and 344,000 net barrels at an average price of $42.31 per barrel in the third quarter of 2016

Costs and Expenses

Total production expense for the fourth quarter of 2016 was $11.8 million, which includes $3.4 million related to workovers performed during the quarter. Total production expense, excluding workovers, was $8.4 million, or $25.60 per BOE of sales, for the fourth quarter of 2016. This is a decrease of $0.9 million compared to $9.3 million, or $19.99 per BOE of sales, for the fourth quarter of 2015 and an increase of $1.1 million compared to $7.3 million, or $21.04 per BOE in the third quarter of 2016. While actual costs declined compared to the same period in the prior year, the cost per BOE rose due to lower sales volumes.

Depreciation, depletion and amortization (DD&A) expense was $1.1 million, or $3.45 per BOE of sales in the three months ended December 31, 2016 compared to $9.5 million, or $20.56 per BOE in the comparable period in 2015, and $1.6 million, or $4.60 per BOE in the third quarter of 2016.

General and administrative (G&A) expense for the three months ended December 31, 2016 was $1.7 million, or $5.22 per BOE, as compared to $2.9 million, or $6.30 per BOE in the three months ended December 31, 2015, and $1.6 million, or $4.55 per BOE in the third quarter of 2016. The Company has taken significant steps to reduce overall G&A costs over the past 18 months, with decreases realized in personnel costs, incentive compensation, services and various other cost categories. General and administrative expense includes $0.1 million, $0.8 million,

and ($0.9) million of non-cash compensation expense for the quarters ended December 31, 2016, December 31, 2015, and September 30, 2016, respectively.

Income tax expense for the fourth quarter of 2016 was $2.4 million compared to $4.2 million for the same period in 2015, and $2.2 million in the third quarter of 2016. The decrease in tax compared to the same period a year ago is primarily attributable to lower revenues in the Company’s operations in Gabon.

Hedging

In order to limit VAALCO’s commodity price risk, the Company added to its hedging position. As of December 31, 2016, VAALCO had unexpired crude oil put contracts covering 792,000 barrels of anticipated sales volumes for the period from January 2017 through December 31, 2017 at a weighted average price of $48.46. The Company recorded a non-cash mark-to-market charge of $0.9 million and $0.2 million related to the existing puts during the fourth and third quarters of 2016, respectively, which was included in other, net in the Consolidated Statements of Operations. The Company has not entered into additional derivative contracts since December 31, 2016.

Year End 2016 Reserves

With the closing of the U.S. property sale, 100% of year-end 2016 reserves were related to oil in Gabon. As oil prices improve in the future, which should extend the economic limit of the Etame Marin block, the Company would expect reserves to increase. VAALCO has numerous identified development drilling locations that would also become economic in a higher pricing environment, which would also potentially reclassify reserves from probable to proved.


	MMBOE
Proved Reserves at December 31, 2015	3.0
2016 Production	(1.5)
Reduction due to lower crude prices	(0.6)
Disposition of U.S. properties	(0.2)
Acquisition of additional interest in Etame Marin block	0.3
Performance additions	1.6
Proved Reserves at December 31, 2016	2.6

Capital Investments/Balance Sheet

During the three months ended December 31, 2016, the Company did not undertake any new capital projects. An offset was recorded, during the fourth quarter, for the Company’s accrual basis capital expenditures totaling $2.1 million, which is primarily related to downward adjustments to capital expense recorded in 2015 in connection to the Company’s prior-year drilling program in addition to current year inventory adjustments. The capital expenditures for the year ended December 31, 2016 on a cash basis were $8.7 million primarily for equipment and enhancements.

At the end of the fourth quarter, VAALCO had an unrestricted cash balance of $20.5 million. This does not include an additional $0.7 million in restricted cash (related primarily to deposits in Gabon) classified as current assets or the additional $0.9 million of restricted cash classified as long term.

At December 31, 2016, debt, net of deferred financing costs, totaled $14.4 million, of which $7.5 million was classified as current, reflecting the repayment terms of the new loan agreement with the International Finance Corporation (“IFC”).

In the fourth quarter of 2016, we adopted ASU 2016-09 related to stock-based compensation. The Company has applied a modified retrospective basis of adoption in which each of the quarters in 2016 have been revised to reflect the application of this new standard and a $1.0 million cumulative effect adjustment was reflected in retained earnings on January 1, 2016. Results for the three months ended September 30, 2016 includes a $0.8 million adjustment to reduce stock-based compensation as a result of this adoption.

NON-GAAP FINANCIAL MEASURES

Adjusted EBITDAX is a supplemental non-GAAP financial measure used by VAALCO’s management and by external users of the Company’s financial statements, such as industry analysts, lenders, rating agencies, investors and others who follow the industry as an indicator of the Company’s ability to internally fund exploration and development activities and to service or incur additional debt. Adjusted EBITDAX is a non-GAAP financial measure and as used herein represents net income before discontinued operations, interest income (expense) net, income tax expense, depletion, depreciation and amortization, impairment of proved properties, exploration expense, non-cash and other items including stock compensation expense and commodity derivative loss.

Adjusted EBITDAX has significant limitations, including that it does not reflect the Company’s cash requirements for capital expenditures, contractual commitments, working capital or debt service. Adjusted EBITDAX should not be considered as a substitute for net income (loss), operating income (loss), cash flows from operating activities or any other measure of financial performance or liquidity presented in accordance with GAAP. Adjusted EBITDAX excludes some, but not all, items that affect net income (loss) and operating income (loss) and these measures may vary among other companies. Therefore, the Company’s Adjusted EBITDAX may not be comparable to similarly titled measures used by other companies.

The table below reconciles the most directly comparable GAAP financial measures to Adjusted EBITDAX.
